Property-Based Testing: Assert the Law, Not the Example

An example-based test checks the cases you thought of, which is exactly the set that excludes your bugs. Property-based testing inverts it: state a law the code must obey for all inputs, let the machine hunt for a counterexample, and let it shrink that counterexample to something you can read. This lesson covers the property patterns, generators, shrinking, and where the technique stops fitting.
